Introduction
1、Product advantage
High-purity magnesium hydroxide uses magnesium chloride as raw material and adopts the brine-ammonia-lime combined method MgCl2+2NH3·H2O→Mg(OH)2↓+2NH4Cl to produce high-purity magnesium hydroxide, which is characterized by high purity, good whiteness, few impurities and uniform particle size distribution.
The modified magnesium hydroxide is benchmarked against internationally renowned brands such as Martin of Germany 、America、and Japan, with a high oxygen index. MDH with a special crystal structure has the characteristics of improving compatibility with polymers, increasing powder filling amount, reducing viscosity and increasing melt index, and improving the tensile, bending, impact and other properties of the product.
